EMISSION CONTROL INFORMATION
To protect the environment in which we all live, Kawasaki has incorporated crankcase emis-
sion (1) and exhaust emission (2) control systems in compliance with applicable regulations of
the United States Environmental Protection Agency and California Air Resources Board. Addi-
tionally, Kawasaki has incorporated an evaporative emission control system (3) in compliance
with applicable regulations of the California Air Resources Board on v ehicles sold in California
only.
1. Crankcase Emission Control System
This system eliminates the release of crankcase vapors into the atmosphere. Instead, the vapors
are routed through an oil separator to the i ntake side of the engine. While the engine is operating,
the vapors are drawn into combustion chamber, where they are burned along with the fuel and air
supplied by the carburetion system.
2. Exhaust Emission Control System
This system reduces the amount of pollutants discharged into the atmosphere by the exhaust
of this motorcycle. The fuel, ignition, and exhaust systems of this motorcycle have been carefully
designed and constructed to ensure an efficient engine with low exhaust pollutant levels.
3. Evaporative Emission Control System
Vapors caused by fuel evaporation in the fuel system are not vented into the atmosphere. In-
stead, fuel vapors are routed into the running engine to be burned, or stored in a canister when
the engine is stopped. Liquid fuel is caught by a vapor separator and returned to the fuel tank.
The Clean Air A ct, which is the Federal law covering motor vehicle pollution, contains what is
commonly referred to as the Act’s "tampering provisions."
"Sec. 203(a) The following acts and the causing thereof are prohibited...
(3)(A) for any person to remove or render inoperative any device or element of design installed
on or in a motor vehicle or motor vehicle engine in compliance with regulations under this
title prior to its sale and delivery to the ultimate purchaser, or for any manufacturer or dealer
knowingly to remove or render inoperative any such device or element of design after such
sale and delivery to the ultimate purchaser.
(3)(B) for any person engaged in the business of repairing, servicing, selling, leasing, or trading
motor vehicles or motor vehicle engines, or who operates a fleet of motor vehicles know-
ingly to remove or render inoperative any device or element of design installed on or in a
motor vehicle or motor vehicle engine in compliance with regulations under this title follow-
ing its sale and delivery to the ultimate purchaser..."
NOTE
○
The phrase "remove or render inoperative any device or e lement of design" has been generally
interpreted as follows:
1. Tampering does not include the temporary removal or rendering inoperative of de-
vices or elements of design in order to perform maintenance.
2. Tampering could include:
a.Maladjustment of vehicle components such that th e emission standards are ex-
ceeded.
b.Use of replacement parts or accessories which adversely affect the performance
or durability of the motorcycle.
c. Addition of components or accessories that result in the vehicle exceeding the stan-
dards.
d.Permanently removing, disconnecting, or rendering inoperative any component or
element of design of the emission control systems.
WE RECOMMEND THAT ALL DEALERS OBSERVE THESE PROVISIONS OF FEDERAL LAW,
THE VIOLATION OF WHICH IS PUNISHABLE BY CIVIL PENALTIES NOT EXCEEDING
$10,000 PER VIOLATION.
TAMPERING WITH NOISE CONTROL SYSTEM PROHIBITED
Federal law prohibits the following acts or the causing thereof: (1) The removal or rendering
inoperative by any person other than for purposes of maintenance, repair, or replacement, of any
device or element of design incorporated into any new vehicle for the purpose of noise control
prior to its sale or delivery to the ultimate purchaser or while it is in use, or (2) the use of the
vehicle after such device or element of design has been removed or rendered inoperative by
any person.
Among those acts presumed to constitute tampering are the acts listed below:
•
Replacement of the original exhaust system or muffler with a component not in c ompliance
with Federal regulations.
•
Removal of the muffler(s) or any internal portion of the muffler(s).
•
Removal of the air box or air box cover.
•
Modifications to the muffler(s) or air intake system by cutting, drilling, or other means if such
modifications result in increased noise levels.
Foreword
This manual is designed primarily for use by
trained mechanics in a properly equipped shop.
However, it contains enough detail and basic in-
formation to make it useful to the owner who de-
sires to perform his own basic maintenance and
repair work. A basic knowledge of mechanics,
the proper use of tools, and workshop proce-
dures must be understood in order to carry out
maintenance and repair satisfactorily. When-
ever the owner has insufficient experience or
doubts his ability to do the work, all adjust-
ments, maintenance, and repair should be c ar-
ried out only by qualified mechanics.
In order to perform the work efficiently and
to avoid costly mistakes, read the text, thor-
oughly familiarize yourself with the procedures
before s tarting work, and then do the work care-
fully in a clean area. Whenever special tools or
equipment are specified, do not use makeshift
tools or equipment. Precision measurements
can only be made if the proper instruments are
used, and the use of substitute tools may ad-
versely affect safe operation.
For the duration of the warranty period,
we recommend that all repairs and scheduled
maintenance be performed in accordance with
this service manual. Any owner maintenance or
repair procedure not performed in accordance
with this manual may void the warranty.
To get the longest life out of your vehicle:
•
Follow the Periodic Maintenance Chart in the
Service Manual.
•
Be alert for problems and non-scheduled
maintenance.
•
Use proper tools and genuine Kawasaki Mo-
torcycle parts. Special tools, gauges, and
testers that are necessary when servicing
Kawasaki motorcycles are introduced by the
Special Tool Catalog or Manual. Genuine
parts provided as spare parts are listed in the
Parts Catalog.
•
Follow the procedures in this manual care-
fully. Don’t take shortcuts.
•
Remember to keep complete records of main-
tenance and repair with dates and any new

1-2 GENERAL INFORMATION
Before Servicing
Before starting to perform an inspection service or carry out a disassembly and reassembly opera-
tion on a motorcycle, read the precautions given below. To facilitate actual operations, notes, illustra-
tions, photographs, cautions, and detailed descriptions have been included in each chapter wherever
necessary. This section explains the items that require particular attention during the removal and
reinstallation or disassembly and reassembly of general parts.
Especially note the following:
(1) Dirt
Before removal and disassembly, clean the motorcycle. Any dirt entering the engine will shorten
the life of the motorcycle. For the same reason, before installing a new part, clean off any dust or
metal filings.
(2) Battery Ground
Disconnect the ground (–) wire from the battery before performing any disassembly operations
on the motorcycle. This prevents the engine from accidentally turning over while work is being
carried out, sparks from being generated while disconnecting the wires from electrical parts, as
well as damage to the electrical parts themselves. For reinstallation, first connect the positive
wire to the positive (+) terminal of the battery
(3) Installation, Assembly
Generally, installation or assembly is the reverse of removal or disassembly. However, if instal-
lation or assembly sequence is given in this Service Manual, follow it. Note parts locations and
cable, wire, and hose routing during removal or disassembly so they can be installed or assem-
bled in the same way. It i s preferable to mark and record the locations and routing whenever
possible.
(4) Tightening Sequence
When installing bolts, nuts, or screws for which a tightening sequence is given in this Service
Manual, m ake sure to follow the sequence. When installing a part with several bolts, nuts, or
screws, start them all in their holes and tighten them to a snug fit, thus ensuring that the part has
been installed in its proper location. Then, tighten them to the specified torque in the tightening
sequence and method indicated. If tightening sequence instructions are not given, tighten them
evenly in a cross pattern. Conversely, to remove a part, first loosen all the bolts, nuts, or screws
that are retaining the part a 1/4-turn before removing them.
(5) Torque
When torque values are given in this Service Manual, use them. Either too little or too much
torque may lead to serious damage. Use a good quality, reliable torque wrench.
(6) Force
Common sense should dictate how much force is necessary in assembly and disassembly. If
a part seems especially difficult to remove or install, stop and examine what may be causing the
problem. Whenever tapping i s necessary, tap lightly using a wooden or plastic-faced mallet. Use
an impact driver for screws (particularly for the removing screws held by non-permanent locking
agent) in order to avoid damaging the screw heads.
(7) Edges
Watch for sharp edges, a s they could cause injury through careless handling, especially during
major engine disassembly and assembly. Use a clean piece of thick cloth when lifting the engine
or turning it over.
(8) High-Flash Point Solvent
A high-flash point solvent is recommended to reduce fire danger. A commercial solvent com-
monly available in North America is standard solvent (generic name). Always follow m anufacturer
and container directions regarding the use of any solvent.
(9) Gasket, O-ring
Replace a gasket or an O-ring with a new part when disassembling. Remove any foreign matter
from the mating surface of the gasket or O-ring to ensure a perfectly smooth surface to prevent
oil or compression leaks.
GENERAL INFORMATION 1-3
Before Servicing
(10)Liquid Gasket, Locking Agent
Clean and prepare surfaces where liquid gasket or non-permanent locking agent will be used.
Apply them sparingly. Excessive amount may block engine oil passages and cause serious dam-
age.
(11) Press
When using a p ress or driver to install a part such as a wheel bearing, apply a small amount of
oil to the area where the two parts come in contact to ensure a smooth fit.
(12)Ball Bearing and Needle Bearing
Do not remove a ball bearing or a needle bearing unless it is absolutely necessary. Replace any
ball or needle bearings that were removed with new ones. Install bearings with the manufacturer
and size marks facing out, applying pressure evenly with a suitable driver. Apply force only to the
end of the race that contacts the press fit portion, and press it evenly over the base component.
(13)Oil Seal and Grease Seal
Replace any oil or grease seals that were removed with new ones, as removal generally dam-
ages seals. Oil or grease seals should be pressed into place using a suitable driver, applying a
force uniformly to the end of seal until the face of the seal is even with the end of the hole, unless
instructed otherwise. When pressing in an oil or grease seal which has manufacturer’s marks,
press it in w ith the marks facing out.
(14)Circlip, Retaining Ring, and Cotter Pin
When installing circlips and retaining rings, take care to compress or expand them only enough
to install them and no more. Install the circlip with its chamfered side facing load side as well.
Replace any circlips, retaining rings, and cotter pins that were removed with new ones, as re-
moval weakens and deforms them. If old ones are reused, they could become detached while
the motorcycle is driven, leading to a major problem.
(15)Lubrication
Engine wear is generally at its maximum while the engine is warming up and before all the sliding
surfaces have an adequate lubricative film. During assembly, make sure to apply oil to any sliding
surface or bearing that has been cleaned. Old grease or dirty oil could have lost its lubricative
quality and may contain foreign particles that act as abrasives; therefore, make sure to wipe it off
and apply fresh grease or oil. Some oils and greases in particular s hould be used only in certain
applications and may be harmful if used in an application for which they are not intended.
(16)Direction of Engine Rotation
To rotate the crankshaft manually, m ake sure to do so in the direction of positive rotation. Pos-
itive rotation is counterclockwise as viewed from the left side of the engine. To carry out proper
adjustment, it is furthermore necessary to rotate the engine in the direction of positive rotation as
well.
(17)Replacement P arts
When there is a replacement instruction, replace these parts with new ones every time they are
removed.
Replacement parts will be damaged or lose their original function once they are removed. There-
fore, always replace these parts with new ones every time they are removed. Although the pre-
viously mentioned gasket, O-ring, ball bearing, needle bearing, grease seal, oil seal, circlip, and
cotter pin have not been so designated in their respective text, they are replacement parts.
(18)Electrical Wires
All the electrical wires are either one-color or two-color. A two-color wire is identified first by the
primary color and then the stripe color. For example, a yellow wire with thin red stripes is referred
to as a “yellow/red” wire; it would be a “red/yellow” wire if the colors were reversed. Unless in-
structed otherwise, electrical wires must be connected to wires of the same color.
